1. A mounting element structure for increasing shock tolerance in a robot comprising a robot tool element mounted on a controllable unit, wherein the mounting element structure, which is configured to be mounted within the controllable unit, comprises:

  • a first surface; and

    a second surface towards the robot tool element,wherein said first and second surfaces are connected with a string assembly consisting of a plurality of strings that establish rigid limits for distances between connecting points on the first and second surfaces, andwherein the strings of the string assembly are arranged so that the string assembly has a geometry that is substantially rigid under exposure to a non-zero external force below a predetermined level defined at least in part by the geometry of the string assembly,wherein some of the strings of the plurality of strings are not parallel to each other between the first and second surfaces under exposure to the non-zero external force below the predetermined level, andwherein increasing an external force from below the predetermined level to more than the predetermined level causes the geometry of the string assembly to transition from being substantially rigid to flexible to reduce damage caused by the external force.
